vice, Whichincludesthe baseboard 5 andlthe panel 6.

for permitting the expeditious and quick assembling of a single tube set including. a.

vario coupler andtwovarioinetersy but it is to be-understood that the board and panel canbe constructed to receive other typesof. receiving sets embodying other difierent parts providing the same does. not depart V the base board 5 by said brackets. jThe from the spirit orthe scope of this invention.

The panel-6 is provided with the necessary recessesvfor,receiving the .shaftsofja rheostat, two variometers andfa vario coupler, and other necessary openings which might Mbe needed; The parts to be placedon the board-such asthe' vacuum tube and socket,

the rheostat,-the vario coupler "and the two variometers havenot been shown, in'view of the fact that the invention consists in'the board for receiving the said parts andthe iconnections therefor rheostat is designated by the referencecharand one which canb'e' upon the market;
